Thanks Niels for your answer. Yes, storm does not support stateful processing components. So, I have to use something like Redis to store it's stateful.

Some of these things have changed over the last 2 years. But comparing the two at this moment would still let me choose Flink.

How many of you that used to use storm as your real-time computing framework, but now, turn to Flink instead. And why ? Could you tell me ? Thank you very much! Thanks zhangminglei
